Reducing Valve-Induced Unplanned Downtime

Jim Cahill

Valves are the critical components in any process manufacturing and production operation that touches what is being produced. As such, they are subject to wear and tear. An ARC View report, Leveraging IIoT Technologies to Reduce Valve-Related Unplanned Downtime highlights key points from a presentation by Emerson’s Shawn Anderson at the ARC Advisory Group’s 20 th Annual Industry Forum. Here is the recap of the report…

Setting Up and Calibrating Valve Positioners

Jim Cahill

Short videos are great ways to show how to perform an activity, such as calibrating a valve’s actuator to move the valve stem based on the 4-20mA signal it receives from the control system. In this under 5-minute “how-to” video , Emerson’s Alex Quah Shu Min demonstrates the setup and calibration procedure for the Fisher 3582i electro-pneumatic, single-acting positioner on a Fisher 667 Size 30 reverse-acting actuator…

Separate versus Integral Final Element Accessories Questions

Jim Cahill

A post from a few years ago, Separate Versus Integral Final Element Accessories in Safety Applications , continues to generate some good questions. I thought I’d make these questions and associated answers more visible in today’s post. Here’s the first question: I understood the whole description, But while calculating PFDavg, We will have to add the Failure rate of valve assembly (Valve+Actuator) which brings…

Mounting Digital Valve Controller Howto Video

Jim Cahill

It has been a busy week as many of the experts around Emerson Process Management here in Austin to work on ways to improve their participation in the social channels. James Holloway I wanted to share a “how to” video, Mounting a Fisher FIELDVUE DVC6200 Digital Valve Controller to a 657 Actuator . In it, Engineering/Industrial Management student and former Emerson intern James Holloway shows the process of mounting…

Does Flow Loop Make Valve Positioner Unnecessary?

Jim Cahill

In the Process Control LinkedIn group, a question was asked : Positioners seem very popular now, but most lines with valves have flow meters attached. Won’t a flow loop make the positioner redundant? When asked for clarification, the original poster explained: As far as I understand them, a positioner simply moves the stem to a particular position governed by the control signal (unlike a ‘non-positioner…

Safety Instrumented System Solenoid-Operated Valve Approaches

Jim Cahill

Last week at the Emerson Exchange conference, I caught up with Emerson’s Riyaz Ali . You may recall Riyaz from many safety instrumented system-related posts . We discussed some of the trends in integrated positioners + solenoid valves + limit switches + valve position transmitters. Riyaz Ali Senior Business Development Manager Riyaz felt that this approach not in line with the safety instrumented system (SIS) general…
